hilitai, with the ideas generated by the other Monks, I was able to come up with this, which worked for me on Win7 strawberry 5.24.1 and linux perl 5.8.5.
#!/usr/bin/perl
use strict;
use warnings;
my $usemod; # if you initialize `my $usemod = 0;`, then the BEGIN
+block's assignment to $usemod is overridden, which you don't want
our $Registry; # this will be overridden by Win32::TieRegistry's expo
+rt of $Registry if in Windows, but
BEGIN {
local $\ = "\n";
if( $^O eq 'MSWin32' ) {
eval {
require Win32::TieRegistry;
Win32::TieRegistry->import( Delimiter => '/' );
$usemod = 1;
}
}
}
if ($usemod) {
my $IEKey = $Registry->{'HKEY_CURRENT_USER/Software/Microsoft/Inte
+rnet Explorer/Main/'};
print "IEKey = '$IEKey'\n";
} else {
print "None of that stuff here\n";
}
- my 5.8.5 linux perl didn't like the use if ... (edit: or, at least, the way I tried... with some debug, it may have eventually worked), so I went with Discipulus's BEGIN block idea to make that run first
- removing the = 0 on my $usemod; allowed the $usemod variable to update in the BEGIN block
- used Perlbotics' suggestion of ->import(), though I included your Delimiter => '/' argument to the import
- made $Registry a package variable using our, which then allowed the Win32::TieRegistry->import() to clobber it with the defined version from the module, while still allowing linux perl to compile the script
edit#2: added use warnings; per best practices
edit#3: added "perl" to "linux perl 5.8.5", so it wasn't implying that was the version of linux, but rather the version of perl
